Eggs should be cooked until both the white and the yolk are firm. And hard boiled eggs should be cooked for at least 12 minutes.

That's where most moms and dads make their first mistake. The fridge just isn't cold enough. Keep eggs refrigerated at least at 40 degrees.

"When you take the eggs home from the grocery store, you put them right in the refrigerator until you're ready to use them" said Schwartz.

And it sounds obvious, but avoid eating raw eggs. That's harder than you might think. Raw eggs are hiding in everything from cookie dough, to salad dressing, to hollandaise sauce might not be properly cooked.

And eat your eggs while they are still fresh and hot, never leave them sitting too long on the table.
